Palm Defender Personal Defenders eliminate the likelihood of accidental OC discharge. The horizontal firing system combined with a wrap-around safety and thumb activated brassswivel preclude unintended activation. Discharging the system requires two separate and distinct operations to disengage the safety and activate the Insert. Personal Defenders are available in six anodized colors: electroless nickel plating and matte black texture. Both Palm and Key Defenders have solid brass swivel activators.
